lMPROtEMENT IN STEAM WATER-ELEVATORS.

Specification forming part of Letters Patent No. 126,246, dated April30, 1872.

Specification describing a certain Improved Steam-Pump, invented byWILLIAM ARTHUR, of Newport, in the county ofGampbell and State ofKentucky.

This invention relates to a pump for raising water by the direct actionof steam; and consists, first, in the construction of the injectingdevice, and, second, in associating therewith an additional injector,whose mouth is placed below the surface-level of the water-supply, sothat it will always be at a temperature sufficiently low to condense thesteam, for a purpose hereinafter explained.

The drawing is a side view of my apparatus partly in section. v

A is the steam-pipe. B is a globe-valve or cock between the steam-pipe Aand the jetnozzle (3, passing centrally across the waterchamber 1). E isa cylindrical portion of pipe leading from the water-chamber D to thedischarge-pipe F, to which water-hose may be coupled. G is thesuction-pipe communicating with the supply-water H, having asurfacelevel, h. Projecting into the supply-pipe beneath the water-levelis a steam-jet, z, the pipe I of which communicates with the steam-pipeA through a valve or cock, K. The steamjet 2' may, if desired, enter thesupply-pipe in a horizontal direction, as shown by dotted lines.

The operation of my pump is as follows: The pipe F is supposed to bealways filled with water that may be retained therein by a check valve,if necessary. To set the pump in operation the valve B is opened, andthe steam issuing from the nozzle G and into the cylindrical neck E willforce the water through the discharge-pipe F. If the water in thechamber D and pipe E becomes heated, owing to its having been long atrest in proximity to the steam-pipe A-and from this cause the steam whenturned on is not condensed with sufficient rapidity to render theinjector efl'ectual-then the valve B is closed and the valve K opened;and by this means the lower steamjet 1' is put in operation, and thisjet, being surrounded by cool liquid, will always be at asufiicientlylow temperature to condense the steam and allow the steamcurrent to gain sufficient momentum to raise or propel the water. Whenthe current is established the valve Bis opened and valve K closed, andthe liquid is pumped by the jet 0 alone, the additional jet i being onlyused for the purpose above mentioned.

The form of the throat or neck E is a matter of paramount importance,because if this is enlarged within a small distance of the nozzle 0 aneddy is formed at the point of enlargement, and more or lessregurgitation takes place.

I claim as my invention- 1. The throat E, having an unvaryin g diameterfrom end to end and discharging into a chamber or pipe, F, of largerdiameter, substantially as and for the purposes set forth.

2. In combination with an upper injector,

O E F, the auxiliary jet I 1', arranged substantially as and for thepurpose set forth.

In testimony of which invention I have hereunto set my hand.

WILLIAM ARTHUR.
